A structure for forming a fluid path is provided. The structure for forming a fluid path according to one embodiment of the present disclosure includes a body configured with first and second fluid paths which communicate with each other, and a third fluid path which is provided at a position, at which the first and second fluid paths are connected to each other, and communicates with the first and second fluid paths, and includes one or more among a first ball which is able to be disposed in the first fluid path, a second ball which is able to be disposed in the second fluid path, and a third ball which is able to be disposed in the third fluid path, wherein a diameter of the first fluid path is greater than that of the second fluid path, and the second ball is able to be disposed in the second fluid path by passing the first fluid path.

Methods, apparatus, and systems for valve trim apparatus for use with control valves are disclosed. An example apparatus includes a valve body including a fluid flow path between an inlet and an outlet. The example apparatus also includes valve trim positioned in the fluid flow path, the valve trim including a first passageway extending from the inlet to the outlet, the first passageway including a first pressure staged passage and a second pressure staged passage, the second pressure staged passage including a first radial passageway.

A solenoid valve for controlling a fluid flow. The solenoid valve comprises an actuating member (101) moveable between a first position and a second position. Movement of the actuating member (101) in one direction effects opening of the valve and movement of the actuating member (101) in an opposite direction effects closing of the valve. The solenoid valve further comprises a biasing means (102) for biasing the actuating member (101) towards the first position; and an armature (103) moveable in response to energising/de-energising of the solenoid valve. Energising the solenoid valve is operable to move the armature (103) to engage the actuating member (101) and cause movement of the actuating member (101) to the second position against action of the biasing means (102). De-energising the solenoid valve allows the biasing means (102) to effect movement of the armature and of the actuating member (101) towards the first position, initially causing disengagement of the armature from the actuating member, and, subsequently causing

Multiport valve with outlets transverse to the inlet useful as a coker switch valve. A sealed lower sleeve assembly provides semi-trunnion ball support. An upper part of the outlet seat recesses is formed in the bonnet, and a lower part in the valve body, which together bias a resilient member to load the seats, independently of end connections. Before bonnet assembly, when the ball is rotated to face a body outlet, there is sufficient space in the seat recesses to insert the seat, slide the seat onto the ball, and then insert the resilient member. When all the seats and resilient members are in place, engagement of the bonnet biases the upper part of the resilient members to load the seat. In valve operation, an enlarged ball outlet bore can straddle two outlet ports and maintain process media flow during switching. Also, methods of assembling, operating, and servicing the valve.

A valve core for a faucet includes a casing, an immovable plate, a movable plate unit, a bracket, and a lever. The movable plate unit includes two pairs of coaxial movable plates and dials. The movable plates are disposed on top of the immovable plate. A restricting mechanism is disposed between one dial and the casing, and another restricting mechanism is disposed between the other dial and the bracket. When the lever is opened, the restricting mechanism is unlocked, and the lever is rotated to adjust the water temperature of a manual spray mode of the faucet. When the lever is closed, the restricting mechanism is locked, and the lever is rotated to adjust the water temperature of an automatic spray mode of the faucet. The water temperature adjustments of the manual spray mode and the automatic spray mode are independent of each other.

A pressure back-up valve (300) includes a release piston (320) movable between first and second stop positions and a closing body (340) movable to a closing position in which this separates first and second connection pressure chambers (327, 326) when the release piston (320) is in a first stop position. The release piston (320) moves the closing body (340), in the second stop position, into an opening position. The release piston (320) is pressurizable on a first pressure surface (A1) from a first side via a third connection pressure chamber (324) and on a second pressure surface (A2) from a second side via a second connection pressure chamber (326). The closing body (340) is pressurized, in the closing position, from a first side via the second connection pressure chamber (326) on a first pressure surface (A4) and from a second side via the first connection pressure chamber (327) on a second pressure surface (A3) of the closing body (34).
